Affiliate Disclosure

MotorCodex is free to use. To keep it that way, some links to products — tools, parts, fluids, scanners — are affiliate links: if you buy through them, we may earn a commission at no extra cost to you.

As an Amazon Associate, MotorCodex earns from qualifying purchases. We may also participate in affiliate programs of parts retailers and tool brands; this page is updated as programs are added.

Commissions never decide recommendations. When we name a part or brand, it’s because it’s what we’d put on our own vehicles — and when the cheapest fix is a $0 cleaning or a gas cap, the page says so. Pages containing affiliate links also carry a disclosure notice where the links appear, per FTC guidelines.
